Compared with the waste-to-heat and electricity-based hybrid refrigeration system, the innovative lab-scale refrigeration system integrated with the DC and AC cooling units that able to use solar and electricity as energy resources. Previous studies found that temperature control and uniform temperature distribution in refrigeration systems are both critical factors reducing vibrio growth on raw oysters and saving energy consumption. Therefore, this refrigeration system also equipped a specially designed divider and was used to test various air circulation strategies to achieve uniform temperature distribution in six individual compartments. The objective is to investigate and evaluate the effects of air circulation strategies and operating conditions on the cooling performance, including temperature distribution, standard deviation of compartment temperatures, and cooling time using a factorial design method. Results indicated the maximum temperature difference between the compartments was 8.9 ± 2.0 °C, 6.7 ± 2.0 °C, and 4.8 ± 2.0 °C in the scenarios of no air circulation, natural air circulation, and combined natural and forced air circulation, respectively. The interaction of fan location and fan direction showed a significant effect on the compartment temperatures while there was no significant effect on cooling time. A circulation fan on the lower part of the 12-volt section with an air supply from the 12- to 110-volt section was determined as the optimal condition to achieve relatively uniform temperature distribution. Refrigeration system also achieved a cooling temperature of 7.2 °C within 150 min to meet regulations. To that end, the innovative hybrid oyster refrigeration system will benefit oyster industries, as well as the aquaculture farmers in terms of complying with regulations and energy savings.

实验室规模混合牡蛎制冷系统的制冷性能分析

与基于废热和电的混合制冷系统相比，创新的实验室规模制冷系统集成了能够将太阳能和电力用作能源的直流和交流冷却单元。先前的研究发现，制冷系统中的温度控制和均匀的温度分布都是减少生牡蛎弧菌生长并节省能源消耗的关键因素。因此，该制冷系统还配备了专门设计的分隔器，用于测试各种空气循环策略，以在六个独立的隔室中实现均匀的温度分布。目的是研究和评估空气循环策略和操作条件对冷却性能（包括温度分布，使用析因设计方法的车厢温度和冷却时间的标准偏差。结果表明，在无空气循环，自然空气循环以及自然和强制空气混合循环的情况下，隔室之间的最大温差分别为8.9±2.0°C，6.7±2.0°C和4.8±2.0°C。风扇位置和风扇方向的相互作用显示出对隔室温度的显着影响，而对冷却时间没有显着影响。确定在12伏区下部的循环风扇，从12伏至110伏区供气，是达到相对均匀温度分布的最佳条件。制冷系统还满足150分钟内7.2°C的冷却温度。为此，
